The APR Stage 2 kit builds upon the Stage 1 upgrade by incorporating additional hardware modifications. This typically includes a high-flow intake system and an upgraded exhaust system, allowing for greater airflow and improved performance.
Testing Methodology
To assess the effectiveness of the APR Stage 1 and Stage 2 kits, we conducted a series of real-world tests. These tests included acceleration runs, dyno sessions, and everyday driving scenarios to evaluate the performance improvements under various conditions.
Acceleration Tests
We performed 0-60 mph acceleration tests for both kits, measuring the time taken to achieve this speed from a standstill. This metric is crucial for understanding the real-world performance gains.
Dyno Testing
Using a dynamometer, we measured the horsepower and torque outputs of the BMW 1M before and after the installation of each APR kit. This data provides a clear picture of the performance enhancements achieved through tuning.
Results of Stage 1 Testing
After installing the APR Stage 1 kit, we observed a significant increase in horsepower and torque. The following results were recorded during our tests:
- Horsepower: Increased from 335 to 400 hp
- Torque: Increased from 332 to 370 lb-ft
- 0-60 mph: Improved from 4.6 seconds to 4.2 seconds
The improvements were noticeable during acceleration, providing a more exhilarating driving experience without compromising drivability.
Results of Stage 2 Testing
With the APR Stage 2 kit installed, the performance enhancements were even more pronounced. The following results were gathered during testing:
- Horsepower: Increased from 335 to 450 hp
- Torque: Increased from 332 to 400 lb-ft
- 0-60 mph: Improved from 4.6 seconds to 3.9 seconds
The Stage 2 kit provided a remarkable boost in power, transforming the BMW 1M into a high-performance machine that rivals more expensive sports cars.
Real-World Driving Experience
In addition to our testing, we also took the BMW 1M equipped with both kits for a series of real-world driving experiences. This included daily commutes, spirited drives on winding roads, and highway cruising.
Daily Commuting
During daily commutes, both the Stage 1 and Stage 2 kits provided a smooth and responsive driving experience. The power delivery was linear, making it easy to navigate city traffic while still having the capability for quick bursts of acceleration when needed.
Spirited Driving
On winding roads, the enhancements from both kits were evident. The increased horsepower allowed for quicker corner exit speeds, while the improved torque made overtaking other vehicles effortless.
Highway Cruising
On the highway, the BMW 1M felt more powerful and confident. The additional horsepower from the Stage 2 kit especially made merging and passing feel incredibly effortless.
Conclusion
